BUILDER-MOTION FOR SPINNING OR WINDING MACHINES;

reassess.

To (law/ 1 0777, it'mag concern Be it known that we, Amen E. BULLOCK and ARTHUR BLAIN, citizens of the United States, residing at Manchester, county of Hillsborough, and State of New Hampshire, have invented an Improvement in Builder- Motions for Spinning or finding Machines, of which the following description, in con nection with the accompanying drawings, is a specification, like characters on the drawing representing like parts.

The invention to be hereinafter described relates to yarn spinning 0r winding machines, and more particularly to the means whereby a bunch may be produced upon the bobbin or bobbins during the spinning or winding operation.

In laying or winding the yarn upon bobbins for subsequent use in the loom, it is sometimes desirable to provide a few pre liminarywindings on the bobbins before commencing the regular or service wind. These preliminary windings are generally known in the art as a bunch, and bobbins so wound are employed in-feeler looms to insure that the last pick laid prior to replenishment of filling shall extend the full width of the cloth. In some feeler looms the bunch may coact with the feeler mechanism, but, so far as the present invention is concerned, these m'attersare innnaterial.

The bunch should be laid by a different lZZEU-"QI'SG of the yarn from that of the regu lar or service wind, and upon completion of the bunch it is desirable that the *tra verse of the regular or service wind shall be automatically resumed. It is also important that the traverse for the bunch be made effective when the spinning or winding operation is started, and with these generally-stated facts in view, animportant feature of the! present invention consists in means between thebuilder motion and yarn guiding devices for effecting a. short traverse of theyarn duringkthe building of the bunch and automatically acting when the hunch is completed to cause-the yarn to be laid in the regular orservice traverse.

Another important feature of the invention consists of a pulley or drum and cam member between the builder motion and yarn guiding means which are locked together during the lninch-lmilding operation and upon the completion of the bunch are unlocked. Still another important feature of the present invention consists of a pulley Specification of Letters Patent.

or drum and a cam member having separate connections with the yarn guiding means and yieldingly held in-locked relation during the bunchbuilding operation, and then relatively moved against the action of the yielding me'ans'to unlock the pulley or drum and cam memberwhen the bunch has been completed thatthe regular traverse may be resumed. 7

Other features of the invention, in addition to the above, will be hereinafter de scribed in connection with the accompanying drawing showing a good, practical form thereof,it being understood that details may bevaried within the true scope of the'invention as definitely set forth by the claims.

The invention is hereinillustrated as employed in connection with a ring-spinning machine, and whileit is particularly well adapted to this type of machine, it is to be understood that it may be employed with advantage in other types of spinning or winding machines.

In the drawing 1- Figure l is a front elevation showing a portion at one end of a ring-spinning machine, having the present invention associated therewith;

Fig. 2 is an enlarged side elevation show ing the pulley or drum and cam member, and their connected parts in the relations assumed at the commencement of the wind ing operation;

Fig. 3 is a view similar to that of Fig. 2, showing the relation of parts after the bunch has been formed and during the regular or service traverse;

Fig, at isan edge view of the pulley or drum, the cam member, and the means for locking them in the relation shown by Fig. 2; and

Fig. 5 is a detached detail showing the means for unlocking the cam member and pulley or drum.

The machine frame for supporting the operative parts may be of any usual construction, and as typified inthe present illustrated form of the invention, is of the usual type of the ring-spinning frame and comprises the end frames 1 connected by the longitudinal rails 2. Mounted on the spin dle rail 3 are a. series of spindles 4, provided with pulleys or whirls 5 by which the spindles may be driven as usual, from any suitable source of power. The spindles l extend upwardly through the ring-rail on the spindles a.

Extending downwardly from the longitu dinal rail 2 is the bracket- 9"having p1votally mounted thereon at 10 the lifter arm' 7 1 or pulled downward by the connection 35 11 carrying the usual counter weight 12. Resting upon the end of the lifter arm 11 is the foot 13 of the lifter rods 14, a roll or pin 15 being employed, if desired, upon which the foot 13 may rest. The ring-rail 6 may extend an indefinite distance longitudinally of the frame and have extending downwardly therefrom a series of lifters 14:

for cooperation with the other lifting arms, as usual in this class of machines; and in order that such lifter arms may operate in unison, the lifter arm 11 is provided with the upwardly-extending arm 16 to which is connected one endof a rod 17 for joining theseveral lifter arms, as usual.

Adjustablysecured to the arm 16 is the extension orarm 18, adjustment being effected by any suitable means such, for instance, as the bolt 19 passing through the arm 16 and the slotted lower portion of the arm 18. The arm 18 carries the-block 20, Fig. 1, to which are secured the ends of the connections leading from the pulley or drum'and the cam member, as will presently appear.

The builder motion proper may be of any usual or desired character, and as shown, comprises the usual builder arm'21 pivoted at 22 to the brackets 23 and 2% which may extend from the machine frame, as indicated. The builder arm carries the usual projection or pin 25 which bears upon the periphery of the builder cam 26 mounted on the shaft 27 properly supported upon the machine frame, as indicated, and driven from any suitable source of power. In the present instance of the invention, the shaft 27 has the bevel gear 28 secured thereto, which meshes with a bevel pinion 29 secured to the operating shaft 30, the construction bein such that upon rotation of the oper- I ating shaft 30, the builder cam 26 willbe rotated, as usual in this class of machines, for operating the builder arm, as well understood by those skilled in the art. The builder arm carries the unwinding drum 31 which is slowly turned by means of the usual worm 32 and pick-wheel which is actuated by the pick pawl 3 1 in. a manner well understood by those skilled in the art, the construction being such that as the builder arm rises and falls under the control ofthe cam 26, the unwinding drum 31 will be rotated stepby-step through the pick-wheel and pick-pawl, for giving back on the flexible connection 35 which connects the unwinding drum 31 to the pulley or drum 36.

Loosely mounted pulley or drum 36 which is joined by the on a fixed stud 37 is the flexible connection or chain 35 with the unwinding drum 31.. The pulley or drum 36 is also connected to the yarn guiding means so that as the pulley or drum 36 is rotated or rocked on its fixed bearing 37, the yarn guiding means will be raised by the weight 12 of the lifter arm and depressed with the builder motion. In the present form of the invention, the pulley or drum 36 has secured to it at 38 the chain or other form of flexible connection 39, the other end of which is secured at 10 to the arm 18 extending from the lifter arm 11.

Also loosely mounted upon the fixed stud 37 is the cam member 41 having the slabbedoff portion 42, and secured to the cam memher at aa is the chain or other flexible connection 44. which is jointed at to the arm 18, the, construction being such that the arm 18 and, perforce, the lifter arm 11 and yarn guiding means, are under the control of the two connections 39 and 44:, one leading from the pulley or drum 36 and the other from H for holding the locking device or pin a5 in its adjusted position. The face ofthe pulley or drum 36 is provided with a recess L7 and a flattened raised portion 48, against the edge 49 ofwhich the locking device or pin 15 is adapted to hear when the parts are in the position indicated in Fig. 2, that is, at

the commencement of the building operation, at which time the flexible connection as leading from the cam member 41 passes over the slabbed=olf portion 42 ofthe'cam memher, the construction being such that as the builder arm rises under the dictates of the cam 26, and lets back on the pulley or drum 36, the cam member 41 follows the pulley or drum 36 and controls the lifting action of the ring-rail 6.

the flexible connection 4 1 leads over the slabbed-oif portion of the cam member 41, the ring-rail will be lifted by the weight 12 a less distance than it would be lifted were the ring-rail under the control of the flexible connection 39 alone, so that the. initial winding under the conditions stated, will be of a shorter traverse than the regular or service traverse.

The cam member 41 in addition to being loosely mounted upon the fixed stud 37, is movable longitudinally on said stud toward and from the pulley or drum 36, and in order to maintain the cam member ll nor- Since, during this backward movement of the pulley or drum 36,

mally pressed toward the pulley or drum36, yielding means are provided. In the present form of the invention this yielding means comprises a spring 50, one end 5101? which is received in an-opening formed in a collar 52 secured to the stud 37 by means such as the setscrew 53, and the other end of said spring is secured by suitable means such as the screw 54, to the cam 1nember'41, the construction being such that while the spring may exert expansive force against the cam member 41 to force the cam member yieldingly toward the pulley or drum 36, it will, nevertheless, yield to permitthe cam member to move longitudinally of the stud 37 away from the pulley or drum36 to thereby unlock the cam member 41 from the pulley or drum 36. I

Various means for causing relative movement of the pulley or drum 36 and the cam member 41 toward and away from each other may be devised within-the scope ofthe invention, but in the present instance thereof, the stud 37 has secured thereto and rising therefrom, a fixed pin 55, Figs, 4 and 5, and the hub portionofthe cam member 41 has a recess 56, the alls of which are beveled or inclined as at 57, Fig. 5, the construction being such that should the cam member 41 be moved clockwise, viewing Fig. 2, to cause the beveled or inclined surface 57 to ride over the fixed pin 55, the caminember 41 will be moved longitudinally on the fixed stud 37' away from the pulley or drum 36 to thereby disengage the locking device 45 from the shoulder 49 of the pulley ordrum.

At the commencement of the winding operation, the parts are in the position indicated by Fig. 2, with the cam member and pulley or drum in locked relation, that is, with the pin 45 bearing against the shoulder 49 of the pulley or drum. As the builder arm lets back on the flexible connection 35, the pulley or drum 36 and perforce, thecam member 41, willturn clockwise, Fig. 2; and since the flexible connection 44 leads from the slabbed-otf portion of the cam member, it will control the rising movement of the ring-rail and give a short traverse to the yarn longitudinally of the bobbins, theconnection 39 between the pulley or drum 3G and the ring-rail becoming slack. On each successive upward movement of the builder arm, the let-back action of the flexible connection becomes greater and greater due to the let-oil drum 31, until, when the bunch has been completed, the beveled or inclined surface 57 of the cam member 41 will meet the fixed pin and force the cam member long udmally away from the pulley or drum 36, thereby unlocking the pulley or drum and the cam member, and the end of the pin 45 will rest upon the surface 48 of the pulley or drum 36, owing to the pull of thellexible connection 44. Thus, duringthe guiding means, means :for :operatively con bunch-building operation, the cam member 4-1 and the pulley or drum 36 are looked in operative relation, and when the bunch has been completed with the desired number of short traverses, the cam member and pulley ordrum will be automatically unlocked and will remain in unlocked position to permit the ring-rail to remain under the control of the flexible connection-39 between the drum and the ring-rail during the remainder of the regular or service traverse.

lVhen the bobbins have been completely wound and dotted and the flexible connection 35 is again wound upon the drum 3:1, preparatory to the commencement of the winding operation, it is desirable that the cam member 41 and the pulley or drum 36 resume their locked condition as indicated in Fig. 2. To this end, the spring 50 has in addition to its expansive actiontor holding the cam member 41 in locked relation with the pulley or drum 36, a torsional'a'etion, tlre construction being such that when the fiexible connection 35 is wound upon the drum 31, the flexible connection 44 becomes slack and the spring 50 asserts its (torsional action to return the cam member 41 into position for engagement of the locking pin back ot'the shoulder 49 of the pulley or drum 36, and the parts are in position to resume or commence the winding operation.

The'construction above described has been found to be a good, practical form of the invention; butit is to be understoodthat the particular character of the locking device and the particulars-of the means for unlock ing the-cam memberand the pulley or drum whenth'e bunchhas been completed, :may be variouslycont-rivedwithin the true scope of the actual invention as definedby the-claims.
